Automatic cooling motor construction having driver connected on the back

Abstract

Disclosed is a motor structure of an automatic heat-radiating backing driver, comprising a motor, a centrifugal fan and a driver; wherein, the motor is provided with a motor body and a rotating shaft which is pivoted on the motor body and protrudes from the front end and the rear end of the motor body, the centrifugal fan is disposed at the tail end of the rotating shaft and is driven by the motor, in addition, the driver is equipped with a shell nested at the outside of the centrifugal fan on the motor body, a plurality of air holes are arranged on the side wall face of the shell, and the air holes include a plurality of air inlet holes far away from the motor body and a plurality of air outlet holes close to the motor body; thereby, the rotating shaft of the motor is rotated and the centrifugal fan is utilized to disperse the heat in the motor driver.

Description

technical field [0001] The invention relates to a rotary power device, in particular to a back-connected drive for driving a centrifugal fan through the rotation of the motor, and a motor for dissipating heat from the drive by air flow. Background technique [0002] Existing devices such as motor drivers or driving devices generally use a heat dissipation structure with added heat dissipation fins to achieve the purpose of heat dissipation. [0003] However, the technical content disclosed in the prior art to solve the heat dissipation problem of the motor driver is to solve the heat dissipation problem by adding structures such as heat dissipation fins, which leads to defects such as increased volume and weight of the overall motor device, and the method The hot air inside the driver cannot be effectively discharged, and its heat dissipation effect is not good. However, if an external fan is used to provide heat dissipation for the motor driver with airflow, it is necessar...

Problems solved by technology

[0003] However, the technical content disclosed in the prior art to solve the heat dissipation problem of the motor driver is to solve the heat dissipation problem by adding structures such as heat dissipation fins, which leads to defects such as increased volume and weight of the overall motor device, and the method The hot air inside the drive cannot be effectively discharged, and its heat dissipation effect is not good

However, if the external fan uses airflow to provide heat dissipation for the motor driver, it is necessary to add a power supply configuration for the external fan, and the external solution also takes up a lot of space, which is obviously inconvenient
